The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Mar 02, 2023, and should be used to calibrate ACS WFC observations taken between Feb 04, 2023 and Mar 02, 2023. |

New ACS WFC CCDTABs were delivered because ACS ISR 2023-01 showed that no corrections are needed to commanding overheads in DARKTIME. These corrections are located in the OVRHFLS and OVRHUFLS columns of the CCDTABs, and are now set to zero. A new postflash reference file, FLSHFILE, is being delivered because new post-flash calibration data was taken in Nov 2022 as part of proposal 16980. The raw darks were separated by EXPTIME and FLASHDUR and combined with ACSREJ to create short and long-flashed superdarks. These superdarks were differenced and scaled to create an intermediate data product that was then smoothed with a local median filter and renormalized to produce the final postflash file. |

These STIS CCD superbias and superdark files are being delivered to ensure that STIS CCD data taken between January 11 2023 and February 9 2023 are properly corrected for the effects of bias noise and dark current. |
